Specification of Letters lPatent.

Application filed October 19, 1911. Serial No. 655,604.

The invention maybe embodied in a combination implement adapted to serve as an improved can opener, adapted to serve also as a knife-Sharpener and adapted to serve also to remove bottle-seals ofv the crown type.

The invention is illustrated in its preferred embodiment in the accompanying drawing, in which- Figure 1 represents a side elevational view of my improved implement; Fig. 2, a bottom view of the handle-less shearing-blade employed; Fig. 3, a broken side elevational view of the device in wide-open condition to enable it to serve as a Sharpener; and Fig. 4

4, a section taken as indicated at line 4 of Fig. 1.

The implement comprises an inner handle-equipped shearing-blade 1 and an outer handle-less shearing-blade2. These blades are united by a pivot 3, and their operative portions are curved laterally, as appears from Fig. 4. The blades are beveled on their non-adjacent surfaces at5 their shearing-edges. The blade, 1 has a penetratingpointV 4, which is blunt or rounded on its upper surface at 5, to prevent tearing the tin.

The blade 2 has its front end equipped with an inwardly offset member 6, which is adapted to overlie the blade -1 When the blades are closed; andsaid blade 2has a heel 7 formed with an inturned flange 8 at its lower edge. To the flange 8 is secured, by a pivot- 9, a freely revoluble anti-skid disk 10, which is roughened, pitted or toothed on its lower surface, as indicated at 11, to prevent slipping on the can.

lhe blade 1 has a shank 12 to which is secured the handle 13. The shank 12 is offset or bent edgewise to angular form, so that the two arms of the. shank are substantially at right angles to each other, the curve being indicated at lffThe arm of the shank, which is adjacent to the pivot, is provided with a heel 14, the lower edge of which is beveled and constitutes a sharpening-edge 15. The upper edge of the heel 7 is beveled, as indicated at 16, and affords.

a sharpening-edge which crosses and c'o-acts with the edge 15, as indicated in Fig.` 3, when the blades are in the open position. At such time, the lower edge of the blade l, at the base portion of the blade, abuts against a shoulder 17, which constitutes they front edge of the flange 8 of the heel 7. `In this condition the angle between the sharpening-edges 15 and 16 is suitable for the purpose of sharpening a knife. IVhile the. implement is being used forthis purpose, the point-ends of the blades may rest upon t-he table, while the knife is drawn through lthe angle formed by the sharpening-edges 15 and 16. At the junction of the heel 14 with the upper arm of the shank 12 and on the under side of the shank is provided a recessV 18, which so intercepts the rear edge of the heel 14 as to aord a hook 19. When desired, the implement may be employed for removing bottle-seals of the crown type. This is accomplished by rest-ing the lower edge o-f the upper arm of the shank 12 on the bottle-cap, bringing the hook 19 into engagement with the downturned flange of the bottle-cap, and pressing downwardly upon the handle, `in which operation the shank 12 fulcrums on the cap, while the hook 19 serves to'dislodge the cap. In the operation of removing a seal thus,'the remote edge ofthe seal is first-lifted from the bottle, so that any of the contents which may escape under pressure, will be directed away from the operator.v

In using the device as a can-opener, the point 4 of the blade 1 is inserted through the cover of the can 20 (Fig.4), and the device is then operated as a shears to cut the cover of the can. Where the operation is on a circular can, the cutting may be performed in a circle adjacent the circumferential wall of the can. In such operation, the antiskiddin g disk 10 rests upon the edge-portion of the can and may rest upon the -cover also. As the cutting progresses, the handle 13 is moved laterally in case of necessity to make the circle of cutting conform to the edge of the can. When this is done, the can-opener which the heel 'ofthehandle-less shearingblade is-xpivote'd, the disk-.serving as a fulcrum, while its corrugations remain embedded in the surface of the can or in the upper edge of the circumferential wall of the can, as the case may be. A space 21 is provided between the heel and its disk and the rear lower portion of the blade 2, as clearly appears from Fig. l, the purpose being to enable the severed edge-portion of the can cover to curl inwardly and clear itself. The diskl 10 may either pass beneath the curled e'dge, or on it, in the latter of which cases the curled edge will be again depressed Ito the level of thel cover as' the operation progresses. After the handle has been depressed in a shearing operation, it is necessary -to elevate it and cause' the blades to open to enable the cutter t0 be advanced. In the opening operation, the offset 6 at the front end of the blade 2 will engage the upper edge of the can, thus preventing vthe blade from slipping down over the outer surface of the cylindrical wall of the can. As the cutter is advanced to take a fresh hold, the disk 10 will turn according to necessity to position itself properly on the can ready to serve as a -fulcrum` for the next shearing operation.

The improved device can be manufactured cheaply, and serve effectively for the three y purposes described above.

The shoulder l5 is adapted to strike the upper surface of the ilange 8, thereby limiting the closing movement of the shearing blades. The member 6 by striking the upper edge of the blade 1 performs the same function.

The `foregoing "detailed description has been given for clearness of understanding only, and no undue limitation should be understood therefrom.

What I ,regard as new and desire to secure i by Letters Patent isl. A can-opener, comprising a handleequipped shearing-blade provided with a penetrating-point, and a co-acting handleless shearing-blade having a heel equipped.

wit-h a movably mounted anti-skid device.

l2. A can-opener', comprising a handle-- Iequipped shearing-blade provided With a penetrating-point, and a co-acting handleless shearmg-blade provided with ya heel,

said blades being curved laterally, and an anti-skid member pivotally connected with said heel.

4. A can-opener, comprising la handleequipped shearmg-blade provided .with a penetrating-point, a co-acting handleless shearing-blade having a can-engaging heel and alsofprovided at its front end with an inwardly oifset member adapted to bear on the can in the operation of opening the blades, and an anti-skid device pivotally connected with said heel.
